Risk management evaluation (covering Annex F of the Stockholm Convention)


The POPRC has approved the risk profile (Appendix E) for the following substances and the first draft risk management evaluations (RMEs) have been made available for comment. The RME provides information on the socio-economic impacts of any control measures considered for this substance.

Comments are therefore sought on alternatives, impacts on society, efficiency and effectiveness of proposed control measures, costs and waste disposal.

1. Dechlorane plus with its syn- and anti-isomers

Dechlorane plus is a polychlorinated flame retardant used since the 1960s. Uses include as an additive flame retardant in electrical wire and cable coatings, plastic roofing materials, connectors in television and computer monitors , and as a non-plasticizing flame retardant in polymer systems, such as nylon and polypropylene plastic.

Previously, the draft risk profiles were reviewed at POPRC meetings in January 2021 and 2022 and it was decided that more information on adverse reactions was needed.

The updated version of this risk profile will be further discussed at the next POPRC meeting, however, in January 2022 the POPRC decided that the risk management evaluation should be drafted.

2. UV-328 2-(2H-benzotriazol-2-yl)-4,6-bis(2-methylbutan-2-yl)phenol

UV-328 is a type of chemical compound called phenolic benzotriazole. It is used as an ultraviolet (UV) absorber to protect surfaces from fading and degradation under sunlight.

This substance is used in products such as:

  • coating products
  • air care products
  • adhesives and sealants
  • additive to plastics
  • personal care products such as sunscreen
  • lubricants and greases
  • waxes and waxes washing and cleaning products

Other environmental releases of this substance are likely to occur from:

  • indoor use (for example, machine wash liquids or detergents, car care products, paints and coatings or adhesives, perfumes and air fresheners)
  • outdoor use, indoor use in closed systems with minimal clearance (e.g. coolants in refrigerators, oil-based electric heaters)
  • outdoor use in closed systems with minimal clearance (e.g. hydraulic fluids in automotive suspension, lubricants in engine oil and brake fluids)
